I am a third-year graduate student in Computer Science at Peking University, advised by Prof. Yuexian Zou. Previously, I earned a B.A. in Environmental Engineering from Sun Yat-sen University.
My research interests include enhancing the general capabilities of Vision-Language Models (VLMs) and building AI agents that can truly perceive and interact with the world. Currently working in LongCat Foundation Model team to build frontier Omni and Vision-Language Model.
